There are lots of different licenses you can get from PRS, all of which cover slightly different things, for slightly different activities – the Pro-dub license, is specifically for DJ’s, specifically for the purposes of covering the “format shutting” aspects of what many DJ’s currently do: “The rights being granted under the ProDub Licence allow individuals to make copies of recordings they own on to various formats.” – the venue will also have a performance license to allow the music to be played.
PRS are encouraging venues to not allow DJ’s to perform if they don’t hold the license – even if there is no legal requirement for them to hold the license (which in some cases there might be, and in some cases there might not be).
The total cost is around £255 per year (incl. VAT, and tax deductible in some circumstances.) the take up seems most prevalent in dance and aerobics instructors…
